it's been a busy morning for crews at the international space station. about 30 minutes ago they grabbed the dragon cargo vehicle and the next step is to lock it down to the station around 9:40 eastern time. there was some glitches when dragon launched friday and that delayed its arrival by about a day but spacex says everything is working now. the unmanned capsule is carrying more than 1,200 supplies for the station crew and their experiments. at the vatican, there will be no customary angelous prayer on this sunday and the windows of the papal apartment will remain firmly closed. the election to pick pope been dict xvi successor has yet to be begin. ben wedemen joining us from outside the vatican. ben, will all the cardinals to select the new pope at the

vatican or are some still making their way? >> some are still making their way. tomorrow morning at 9:30 the congregation of cardinals, which include 207 cardinals, the it21 will participate are expected at 9:30 in the morning and holding two sessions tomorrow. the afternoon one begins at 5:00 and we don't know how long these meetings of cardinals will actually go. obviously, one of the important points on their agenda will be to set a date for the conclave, but they're also discussing a variety of issues of importance to the church. obviously, the agenda has not been made public, but we're told they will be talking about governance or management of the church, financial issues and pedophile priests and a lot to discuss in addition to the conclave, which they have to set a date for.

brianna. >> we have some familiarity since it hasn't been that long, but walk us through this new process of picking the new pope which will be part of this conclave. >> once the conclave date is set, all the wheels will be set in motion, there is 115 cardinals that will be taking part in the conclave. they will be in a special state and a special hostile within the vatican city where they have no access to cell phones, land lines, internet, blackberry, newspapers, radio, television. they'll be in a completely sealed bubble. and they will walk every day from that hostile to the cystine chapel, which will be prepared for them and there in the cystine chapel on the first day they will vote once and after that, it's four votes a day until they come up with a successor to benedict. now, obviously, all of this in

complete secrecy. we will know when they will have made a decision when you see that white smoke coming out of the chimney over tchapel. last time when pope benedict was elected it took 11 days back in the 13th century it took two years, nine months and two days. any time between those two spans of time. so, no idea, really, how long the process will take. >> ben, as you sit there waiting for that white smoke, we do hope it take less long than perhaps that second option there. ben, we'll be checking in with you. thanks for that. back here at home most people chased out of their home by a brush fire are back at home this morning. firefighters near daytona beach, florida, say they have it 75% contained. at one point 300 families who had to leave. a stretch of i-95 back open.

it was closed because of the thick smoke. so far, no injuries and no reports of any injuries and only a barn and chicken coupe has burned down. authorities say the ground is so unstable that it is too dangerous to look for jeff bush's body. demolition crews will start tearing down the house. >> county officials here say they wish they could have done more but they could not risk any more lives. with that, the official search for jeff bush's body has ended. now, the reality is that no one had been inside that house since thursday when the sinkhole opened up, but what they were doing was around the periphery testing with electronic devices, listening devices, ground penetrating radares to see if they could find where there was stability. if there was enough stability to get back into the house to search for the body. that did not happen.

what they are doing now is moving to what they are calling a demolition phase. they'll bring in heavy equipment and start the demolition process of that house. now, one of the engineers here said that, and he is a sinkhole expert, as well, said that this was a very, very unique sinkhole. >> this is an incredibly unusual condition. i've been doing this for a long time and i've never seen one like this condition. >> right now, measures about 20 feet ride and about 50 feet deep they are saying. if there is any good news, beyond the initial house where the sinkhole was and the houses on either side, they don't believe from testing from the soil that any other houses would be compromised. but it is very unlikely that any of the people living in those three houses will ever go inside them, again. a county official says the ground is so dangerous that crews zil to tear down the house from a distance and they won't

undoubt undoubtedly, he will mention this today. over a portion of the 1965 voting right act, section 5 which gives the government oversight in certain states and certain cities and one area in alabama, shelby county says that is burdensome. the federal government saying that those laws are still needed to make sure that everyone has a part of the franchise and is able to vote freely. we'll hear from him today. he had no idea that america will be fighting and refighting so many fights that he thought would be settled. part of what he will talk about today, but also recognize this area's role in the civil rights movement. >> victor, do we have a sense of how big these crowds are going to be and how they might compare to other years? >> historically, thousands of people here at what is called the bridge crossing jubilee in selma. so many come to recognize what

happened on march 7th when about 600 peaceful protesters tried to make that 54-mile walk from selma to montgomery, but got as far as the bridge when they were beaten down. 17 had to go to the hospital. one was congressman john lewis. he will be here today. in the past we've seen presidents and president clinton in the last few months of his administration. he was here in 2000 and 2007 barack obama and hillary clinton were here at the start of the 2008 presidential campaign. so, political leaders, civil rights leaders and thousands of people honoring the work done here in 1965. those are the people expected to be here today. >> victor blackwell in selma, alabama, thanks, victor. it's a race that brings out some of the toughest, hardiest, most ferocious athletes in the world and most of the competitors aren't even human. it could mean nothing else but alaska's great iditarod.

they thought they were prepared for ryan kelly's return, but they were not. torched miami for 36 points and duke really just with this win proves that they're still a title threat to the rest of the college basketball landscape and coach k. after the game really praised kelly for doing it essentially at all. >> me saying spectacular or whatever doesn't do his performance justice. one for the age as. probably as good a performance as any player has had, a duke player has had. >> all right, so you talk about performance. what a difference a week makes. after reporting the fastest laptime danica patrick is struggling in phoenix this week. finishing 40th out of 43 cars and her practice runs have been pretty slow, as well. not all bad for danica. last year started 37th in this

race and finished 17th, which was her best series cup finish of the season. she has her work cut out for her. if there is one track she knows best is this one in phoenix. instead of settling for the overtime in baylor, they went for the big win. plan to get the ball inbounds to one of their teammates and the ball goes out of bounds and kansas state gets the ball back and they get a chance to win this game. what do they do? shoot the three-pointer at the buzzer and end up getting the win. one of those things where you say we should have gone for overtime and settled it there. but instead we give it to the team and let them pull off the awesome win. when the ranking comes out tomorrow, you can expect gonzaga it be the nation's new number one team, but the question is, is a healthy duke team with the addition of ryan kelly the best in the country? they debate about it at bleacherreport.com. i can tell you, come the end of march when the tournament starts and you fill out your bracket,

no number one is safe. one of the whacky years in college basketball. it will be fun watching all the crazy upset wins come march madness. >> i generally do my bracket like this. perfect. back to danica, i was excited to see her last week in daytona. she is inconsistent. big showing last week. >> which is surprising because she owns a home in phoenix. she is resting in her own bed and she knows this track very well. people are surprised she is not doing well. >> i bet mentally it's tough coming off a good performance like last week and maybe that has something to do with it. >> a lot of pressure. >> a lot of pressure. joe carter, thank you. disgraceful, disgusting and troubled. those are just some of the comments that flooded on to twitter after this t-shirt appeared on amazon's uk website. find out what the tea-shirt's r faced maker is saying. ♪

without a pope. it's not clear when there will be a new pope since the election hasn't been set yet. some of the cardinals who are supposed to vote aren't even in the vatican yet, but those top secret meetings are supposed to start tomorrow. john allen joining us now from rome. he's cnn senior vatican analyst and senior correspondent for the national catholic reporter. john, what is the mood like there without a pope? this must be kind of strange. >> brianna, a weird, in between time. in one way the mood is kind of quiet. in this town, the pope is more or less the star of the show. when there's no pope, in a sense, there's no show. but on the other hand, this is also campaign season for the catholic church. also a lot of excitement in the roman air about what might be going on behind the closed doors when the cardinals get together and, ultimately, who the next pope is going to be. >> a lot going on and a lot of meetings and a whole lot to do. who is running things in the

vatican? i am assuming the lights are still on. >> yes, continuity of power in the vatican. when there is no pope, the empty seat, power to govern the church resides in the college of cardinals. now, of course, that's a body of 207 guys as of today. so, there is a smaller group composed of the dean of the college of cardinals and an official, basically the chamberlain and a couple other vatican officials that are the executive committee that will make day-to-day decisions. it should be stressed, this is no more than routine mantance. all the policy decisions, like issuing teaching documents or naming, all of that is on old until a new pope is in charge. >> that's why they want to have a new pope by easter. are they rushing the process along to make sure that happens, john? >> i think there is a certain rush spirit in the air, not only

because they want to have a new pope in place for holy week, which begins with palm sunday on the 24th, but, also, of course, because they don't want to project an image of being disunified and paralysis and gridlock and chaos to the world. so, i think all the cardinals feel some degree of pressure to get this done. on the other hand, none of them can actually control how long this is going to take because there is no shot clock in a papal election. the way this works, they have to keep going, keep balloting until someone passes that magic two-thirds threshold, which in this case, would be 7 7 votes to become pope shortest one took two hours and the longest was almost three years. the truth of it is, as much as they might like to speed this along, ultimately no one, including the cardinals, knows exactly how long it will take. >> no shot clock in a papal election, although that would be very interesting, i have to say. john allen in rome, thank you for that.

a big rendezvous in space. the crew grabbed the dragon cargo vehicle. the next step is to dock it and lock it. that should happen later this morning around 9:40 eastern time. there were some glitches when dragon launched initially on friday and that delayed arrival by about a day. spacex says everything is working just fine now. the unmanned capsule is carrying more than 1,200 pounds of supplies for the station crew. two cell phones could become smoking guns in the oscar pistorius murder trial. a paralymian is on trial. how the phones could hold the real story. >> he does not verify the cell phone information hof the deceased. >> reporter: during oscar pistorius' bail hearing, the magistrate frustrate would the

enough, he says, to make or break pistorius' case. >> in this particular case, the phone could become the smoking gun, so to speak. >> reporter: it wouldn't be the first time a cell phone was the smoking gun. in 2006, popular musician and theater director peterson was shot dead. his wife convicted after her cell phone tracked her precise muc movements. downstairs making calls when she said she was asleep in bed. today cell phone technology is even more sensitive. pistorius' movement already on public record. pistorius' affidavit was read out from here in the courtroom and his movements that night. at 10:00 p.m., he said he was in the bedroom. in the early morning of the hours hearing a noise and going to the bathroom and firing the shots and then going back to the bedroom to put on his prosthreating legs and then going back to the bathroom and

this weekend queen elizabeth became ill and she had to cancel her appearance at a ceremony in wales. the queen is 86 years old now and some people wonder if she will ever give up the throne,

perhaps. she is known for honoring her commitment. so, canceling an appearance is pretty unusual for her and this has some people wondering certainly how she's doing and with us to talk about that is nadia, our editorial producer. so, what exactly is wrong? >> the queen has gast gastrointroitis. >> what does that mean. >> she is not going to be going -- >> it happens even to royalty. >> as you said. but the reality is for her to cancel a commitment is very unusual and she knows how much trouble these people go to, especially at such short notice. but we understand she's not desperately ill, but she is uncomfortable. >> it is a bit of a big deal. she is in her 80s, 86 now. about the same age about the pope that just abdicated. but do you think we'll ever see her step down? >> never. you'll never see queen elizabeth step down. in fact, the even word is to boo

in the palace. queen elizabeth was 10 years old when her uncle, eduard viii did abdicate. he was the first in 1,000 years. for the entire palace at the time it was traumatic and it was a horrible abdication and it caused enormous riffs in the monarchy and that's how her father, george, became king. but she remembers the trauma well and the dishonor it brought on the family. >> but what in, i actually thought that was covered pretty interestingly in the king's speech. you kind of got the sense of how horrific it would have been from her perspective, but what happens if she does become really ill or in capacitated? >> she appoints a regent. one assumes charles would become regent but still retain the title of the queen. when she had her coronation in 1953, then she took an oath

under god to reign england and the commonwealth countries. for her that is sacred duty above all us. >> she takes it very seriously. what about in holland recently, queen beteroatrice. >> different rules. in the netherlands the different culture, different customs, different rules. in the netherlands, you are not monarch for life, but queen elizabeth is the sovereign for life and, eventually, one assumes charles will then become king and then after that william and then kate and william being pregnant right now, whether they have a son or daughter will become the next monarch. what's happening as we speak, the 16 commonwealth countries are going to approve the fact that it may be a daughter becoming the next monarch. >> interesting. very interesting. it sound like, for instance, even if she were to get further up in years and it becomes too

much for her. she remains the monarch and charles takes over. >> she delegates some of her duties, which she has already done. you will see queen elizabeth as queen until the day she dies. this week's cnn hero spent 13 years delivering babies before a back injury forced her to stop. didn't really stop her, though. now she found a new way to bring mothers and babies through child birth. meet dr. laura. >> there is a traditional saying when you become pregnant that you have one foot in the grave. so many women dying in child birth in many communities. childbirth is feared. >> four women died from pregnancy complications. >> when i went to africa and i saw these women one after another coming in with complications and we didn't have adequate light to treat them.

>> welcome to the world. a lot of the clinics don't have any electricity. midwives use kerosene laterns and use cameras and cell phones to deliver babies. once i witnessed the things i saw, i had to do something about it. my name is laura stachel. i am providing light source so mothers and babies can be saved during child birth. hospitals and clinics receive the solar suitcase for free. the charge controller is very important. provides medical quality lighting and charges cell phones and has a small battery charger for head lamps and for the fetal doppler that we include. perfect. that's it. mothers are now eager to come to the clinics. just shifted the morale of the health care worker. >> this light is going to bring good changes. it keeps me going. >> turn this on. there you go.
